Panels are fabricated with a double interlocking tongue and grove joining system.

Insulation

The panel-insulating core is a Class A urethane, foamed-in place between two metal skins with adhesion to each skin to provide a composite structural action of the panel components.

Trim

Metal Flashings and Closures can be extrusions or factory formed from the same material as the face panel.

Fastening

Panels are secured with a two-component epoxy thixotropic adhesive that has very high shear and peel strength. Tek screw (self-drilling screws similar to sheet metal screws but have a "drill bit-style" point that can drill its own pilot hole) can also be used but are more labor intensive. The screws are zinc or cadmium plated. Flashing and accessories are installed with zinc or cadmium plated sheet metal screws and/or diameter pop-rivets as per manufacturer’s standard practice.
